Solche Alkylenreste können als α, /S-Alkylenreste bezeichnet werden. —-NR3R4 bedeutet eine Dialkylaminogruppe, in der die Alkylgruppen R3 und R4 gleich oder verschieden sein können. Die Alkylreste R3 und R4 können auch zusammen mit dem Stickstoffatom eine cyclische Aminogruppe bilden, z. B. die Piperidino-, Morpholino-, Pyrrolidino-, Piperazino- oder ThiomorphoHnogruppe. Solche cyclische Aminogruppen können als· äliphatische heterocyclische Aminoreste aufgefaßt werden, da sie nicht vollständig konjugiert ungesättigt sind, keine aromatischen Eigenschaften aufweisen (vgl. Gilman »Organic Chemistry*, 2. Auflage, Bd. I,in which R is low molecular weight alkyl radicals or hydrogen atoms. Such alkylene radicals can be referred to as α, / S-alkylene radicals. —NR 3 R 4 denotes a dialkylamino group in which the alkyl groups R 3 and R 4 can be identical or different. The alkyl radicals R 3 and R 4 can also form a cyclic amino group together with the nitrogen atom, e.g. B. the piperidino, morpholino, pyrrolidino, piperazino or thiomorphoHno group. Such cyclic amino groups can be understood as äliphatic heterocyclic amino radicals, since they are not completely conjugated unsaturated, have no aromatic properties (cf.

Kalium bzw. Lithium bedeutet. Die Aminoketone können als freie Basen oder in Form ihrer Salze, z. B. der Hydrochloride, verwendet werden. Wenn Salze der Aminoketone verwendet werden, dann wird ein Teil der metallorganischen Verbindung durch die Säure verbraucht, was aber kein ernster Nachteil ist, da allgemein ein Überschuß an metallorganischer Verbindung angewendet wird.60, reacts to form tertiary alcohols, especially Grignard compounds in which M takes the place of Magnesium halogen group, as well as cycloalkyl and Arykiatrium-, -potassium or -lithiumverbindungen in where M is sodium or potassium or lithium. The aminoketones can be as free bases or in the form their salts, e.g. B. the hydrochloride can be used. If salts of the aminoketones are used, then part of the organometallic compound is consumed by the acid, but this is not serious The disadvantage is that an excess of organometallic compound is generally used.

Die Aminoketone, die das Ausgangsmaterial für die Herstellung der erfindungsgemäßen Aminoalkohole bilden, können nach bekannten Methoden synthetisiert werden. Eine einfache Methode beruht auf der Mannich-Reaktion; z.B. wird a-(Diäthylarninomethyl)-2-propiothienon aus Äthyl-2-thienylketon, Formaldehyd und Diäthylamino-hydrochlorid und j8-Methylamino-propiophenon aus Acetophenon, Formaldehyd und Methylamin-hydrochlarid hergestellt.The amino ketones, which are the starting material for the preparation of the amino alcohols according to the invention form can be synthesized by known methods will. A simple method is based on the Mannich reaction; e.g. becomes a- (diethylaminomethyl) -2-propiothienone from ethyl 2-thienyl ketone, formaldehyde and diethylamino hydrochloride and j8-methylamino-propiophenone from acetophenone, formaldehyde and methylamine hydrochloride.
Nach einer anderen Methode werden nach Friedel-Crafts ^-(tertiär-Amino)-acylhalogenide mit aromatischen Verbindungen gemäß der Methode von D almer und Mitarbeitern (vgl. die Patentschrift 629 054) umgesetzt. Beispielsweise wird jS-Dimethylaminobuttersäure (vgl. Decombe, Annales de Chimie, 10, Bd. 18, S, 145, [1932]) mit Thionylchlorid in das entsprechende Säurechlorid-hydrochlorid übergeführt und dieses mit Benzol in Gegenwart von Aluminiumchlorid zu ß-Dimethyläminobutyrophenon kondensiert.Another method is according to Friedel-Crafts ^ - (tertiary amino) acyl halides with aromatic compounds according to the method of D almer and employees (see. Patent 629 054) implemented. For example, jS-dimethylaminobutyric acid is used (see. Decombe, Annales de Chimie, 10, Vol. 18, S, 145, [1932]) with thionyl chloride in the corresponding Acid chloride hydrochloride converted and this with benzene in the presence of aluminum chloride condensed to ß-dimethyläminobutyrophenone.
Ein dritter Syntheseweg benutzt die Addition von Aminen an α, jS-ungesättigte Ketone, wobei /S-Aminoketone entstehen; so erhält man z. B. durch Addition von Piperidin an Crotonophenon ß-Piperidinobutyrophenon. A third synthetic route uses the addition of Amines to α, jS-unsaturated ketones, where / S-aminoketones develop; so you get z. B. by addition of piperidine to crotonophenone ß-piperidinobutyrophenone.
Die nach dem erfindungsgemäßen Verfahren hergestellten Verbindungen werden im allgemeinen in Form wasserlöslicher Salze von solchen Säuren verwendet, deren Anionen nicht toxisch wirken. Üblicherweise sind die Hydrochloride Jür diese Zwecke geeignet, da sie im wesentlichen beständige, weiße kristalline Stoffe darstellen, die sich in Wasser lösen und leicht peroral oder parenteral verabreicht werden können. Andere Säuren, die nicht toxische Salze bilden, sind Schwefel-, Phosphor-, Citronen-, Wein-, Sulfamin- und Bromwasserstoffsäure. Diese Salze können nach den üblichen Methoden zur allgemeinen Herstellung von Salzen therapeutisch wirksamer Amine bereitet werden. Im folgenden soll die Durchführung des erfindungsgemäßen Verfahrens an Hand von Beispielen näher erläutert werden.Those produced by the process of the invention Compounds are generally used in the form of water-soluble salts of such acids, whose anions are not toxic. Usually, the hydrochlorides are suitable for these purposes, since they are essentially stable, white crystalline substances that dissolve in water and are easily absorbed orally or can be administered parenterally. Other acids that form non-toxic salts are sulfur, Phosphoric, citric, tartaric, sulfamic and hydrobromic acids. These salts can be used according to the usual Methods for the general preparation of salts of therapeutically effective amines are prepared.
